I'm a guy's guy; tough and manly. So, when I started having these thoughts, I tried to rationalize them. I love getting oral sex and my wife is terrific at giving. She says she really enjoys it and gets aroused doing it. I rationalized that my thoughts were just my way of trying to understand what my wife was experiencing. Then I started to get jealous of her. I began to think that I was missing out on something and that I deserved to have the same feelings and excitement that had. The dreams were soon to follow. I would find myself dreaming about sucking another man's cock, often waking up with a raging hard-on. The thoughts persisted and soon I was masturbating while imagining going down on another guy. I swear my orgasms were more intense with these thoughts too. When at the gym, I found myself comparing my package to the other men. I was always careful to steal a brief glance in the shower or to discreetly look in the mirror as men passed by. The thoughts would overcome me as I sat in the sauna and I often had to conceal my hard-on with a towel. Some of the men that I saw at the gym would invade my thoughts and fantasies at night. The thoughts were coming more often and they soon became an obscession. I found myself visiting internet sites that catered to pics of naked guys. I looked intently at the pics, lusting after the cocks that were displayed before me. I would find one or two pics of a beautiful cock and I would jack-off imagining myself sucking it until it came. I progessed to the gay and bisexual sites where I could check out the pics and movies of men sucking each others rock-hard cocks and pounding each others asses. Then the gay/bisexual chat rooms. I started cybering with other men, jacking off with one hand and typing with the other. This was extremely difficult to do at home and I had to choose my moments wisely. How I never got caught is beyond me. These thoughts and fantasies came and went over the years but each time they returned, the feelings were more intense and urgent. It was as if I sensed that time was passing by and action was in order.
